SwivelCheck can operate in automated or manual mode, and includes API’s Intellicomp software for control, data acquisition and reporting. The device can also be used in conjunction with the API XD laser interferometer to measure horizontal rotary table position. SwivelCheck can be mounted off-centre of the rotating axis to measure the swivel axis of trunnions without any need for the disassembly of critical machine-tool components.

API says that SwivelCheck is easy to set-up, offers ±400° swing and allows tilting axes to be checked at the spindle nose, thus offering true accuracy to be reported over systems that check at the motor and do not detect ‘lost motion’. The Intellicomp software provides a direct import of measured axis data to machine-tool controllers, allowing an update of system parameters for improved precision.
